Steve Spangler Science: Growing and Shrinking Marshmallows

Vacuum packing Peeps marshmallows is an incredible (and delicious) demonstration of air!

A vacuum packer is an amazing device that vacuum packs food to seal in the freshness. At least that’s what those late night infomercials tell us. We’re more excited about using this fascinating device to explore the amazing properties of air pressure. Fill the special storage container with marshmallows (we prefer those adorable Peeps) and remove the air. Watch out! It’s the incredible growing marshmallow trick!

Adult Supervision Required – Not many kids have their own kitchen vacuum packer, so it goes without saying that adult supervision is required. Hey kids, you’ll have to fight for time with the vacuum packer machine after Mom and Dad figure this one out! Be sure to read and follow the manufacturer’s directions for using your specific kitchen vacuum packer.
